Simultaneous optical pulse compression and wing reduction
(AIP Publishing, 1986-03-31)We report the compression of picosecond optical pulses with a simultaneous reduction of the pulse wings by using a combination of both the self-phase modulation and nonlinear birefringence effects in a modified optical-fiber ... -
Enzyme-linked immunosorbent assay for detection of serum antibodies to Pasteurella haemolytica cytotoxin (leukotoxin) in cattle
(American Society for Microbiology, 1986-08)An enzyme-linked immunosorbent assay (ELISA) was developed for detection of bovine serum antibodies to the cytotoxin (leukotoxin) of Pasteurela haemolytica. A partially purified, cytotoxic, and immunogenic protein obtained ... -
Filter paper dot-immunobinding assay for detection of Spiroplasma citri
(American Society for Microbiology, 1987-01)A rapid filter paper dot-immunobinding assay was adapted to detect the wall-less mollicute Spiroplasma citri in medium, plants, or insects. Filter paper spotted with sample was incubated first in dilute antiserum, then in ... -
Effect of repeated in vitro transfer of Pasteurella haemolytica A1 on encapsulation, leukotoxin production, and virulence
(American Society for Microbiology, 1987-01)Pasteurella haemolytica serotype 1 was transferred daily for 128 serial passages on both unsupplemented brain heart infusion agar and the same basal medium supplemented with bovine blood, horse serum, and yeast extract. ... -
Comparison of TRACK XI fluorometric immunoassay system with other serologic tests for detection of serum antibody to Brucella abortus in cattle
(American Society for Microbiology, 1987-02)The TRACK XI system (TRACK) is a commercially available fluorometric immunoassay system that has been adapted for the detection of antibodies to several antigens in various animal species. Serum antibodies to Brucella ... -
Characterization of the Pseudomonas aeruginosa recA analog and its protein product: rec-102 is a mutant allele of the P. aeruginosa PAO recA gene
(American Society for Microbiology, 1987-04)We cloned a 2.3-kilobase-pair fragment of the Pseudomonas aeruginosa PAO chromosome which is capable of complementing recA mutations of Escherichia coli. The recA-complementing activity was further localized to a ... -
Ultrafast light-controlled optical-fiber modulator
(AIP Publishing, 1987-04-06)We report the ultrafast operation of a light-controlled optical-fiber modulator, driven by subpicosecond, compressed, and amplified (6000 A) dye laser pulses, controlling frequency doubled (5320 A) yttrium aluminum garnet ... -
Cloning and characterization of the cl repressor of Pseudomonas aeruginosa bacteriophage D3: A functional analog of phage lambda cI protein
(American Society for Microbiology, 1987-05)We cloned the gene (cl) which encodes the repressor of vegetative function of Pseudomonas aeruginosa bacteriophage D3. The cloned gene was shown to inhibit plating of D3 and the induction of D3 lysogens by UV irradiation. ... -
Potential for transduction of plasmids in a natural freshwater environment: Effect of plasmid donor concentration and a natural microbial community on transduction in Pseudomonas aeruginosa
(American Society for Microbiology, 1987-05)Transduction of Pseudomonas aeruginosa plasmid Rmsl49 by the generalized transducing bacteriophage phi-DS1 was shown to occur during a 9-day incubation of environmental test chambers in a freshwater reservoir. Plasmid DNA ... -
Far infrared spectroscopy with subpicosecond electrical pulses on transmission lines
(AIP Publishing, 1987-08-17)Optically generated and detected electrical pulses on transmission lines in the subpicosecond range have frequencies extending up to 1 THz, thereby covering the far infrared region of the spectrum from 0 to 30 cm^-1. We ... -
Electromagnetic shock waves from transmission lines
(American Physical Society, 1987-10-12)We have observed subpicosecond electrical pulses to propagate on 5-pm coplanar transmission lines at velocities faster than the phase velocity in the underlying dielectric. This situation produces an electromagnetic shock ... -
Autoxidation of tetralin in water catalysed by cobalt(ii)-pyridine complexes bound to polymer colloids
(Royal Society of Chemistry, 1988)Cobalt(ii)-pyridine complexes bound to 60 nm diameter latex copolymers of styrene, divinylbenzene, and either acrylic or methacrylic acid catalyse autoxidation of tetralin in water faster than cobalt(ii)-pyridine complexes ... -
Contractible open 3-manifolds which are not covering spaces

Dark-pulse propagation in optical fibers
(American Physical Society, 1988-01-04)We report measurements of the reshaping of 0.3-psec dark pulses due to their passage through 10 m of single-mode optical fiber. The measurements were performed as a function of intensity and the observed strong reshaping ... -
Measurement of ultrafast hot-carrier relaxation in silicon by thin-film-enhanced, time-resolved reflectivity
(AIP Publishing, 1988-01-04)Time-resolved reflectivity measurements within ~100 fs resolution have revealed an initial 350 fs relaxation time in silicon, believed to be the time it takes hot, photoinjected carriers to relax to the band edge. The ... -
Capacitance free generation and detection of subpicosecond electrical pulses on coplanar transmission lines
(Institute of Electrical and Electronics Engineers, 1988-02)Based on a reanalysis of previous work and new experimental measurements, we conclude that the parasitic capacitance at the generation site is negligible for sliding contact excitation of small dimension coplanar transmission ... -
Characterization of the Pseudomonas aeruginosa recA gene: The Les- phenotype
(American Society for Microbiology, 1988-02)The Les- phenotype (lysogeny establishment deficient) is a pleiotropic effect of the lesB908 mutation of Pseudomonas aeruginosa PAO. lesB908-containing strains are also (i) deficient in general recombination, (ii) sensitive ... -
